your thoughts on doing Triple bypass

Hi there everybody, I thought I might post here and get your ideas, thoughts, opinions, etc. on doing a ride my buddy told me he wants to do sometime called the Triple Bypass. As I understand from him it's a one day 120 mile ride that passes 3 mountain passes out in colorado. I got the idea of possibly doing it on my bike friday NWT with him.

I'd especially be interested if any of you that live in colorado or have done this ride on a folding bike, what your expierences etc, are.
